Method and device for switching an item of application data

Abstract

A method for switching an item of data relating to an application transported in a data fragment of a packet of a stream transport protocol, such as the Stream Control Transport Protocol. The method is implemented by a multiplexing device able to transfer data relating to a plurality of applications to processing entities, using a first destination port identifier common to the plurality of applications, and, in a data fragment, a second identifier specific to the application.

         7 . The switching method as claimed in  claim 1 , wherein the first destination port identifier is a port identifier allocated for an application based on the SCTP protocol. 
     
     
         8 . A configuration method comprising:
 configuring a packet of a Stream Control Transport Protocol stream transport protocol, the packet comprising a header and a data fragment, the configuring being implemented by a terminal device able to transmit a datum relating to an application to a multiplexing device, and comprising:   parameterizing the packet with a first destination port identifier in the header and with a second identifier specific to the application in the data fragment; and   transmitting the parameterized packet to the multiplexing device.   
     
     
         9 . The configuration method as claimed in  claim 8 , furthermore comprising receiving an error message if no application is determined by the multiplexing device based on the first identifier and the second identifier that are parameterized. 
     
     
         10 . A switching device able to transfer data relating to a plurality of applications to processing entities, one of the data being transported in a data fragment of a packet of a Stream Control Transport Protocol stream transport protocol, comprising:
 a receiver configured to receive, from a terminal device, the packet of the stream transport protocol comprising a header containing a first destination port identifier common to the plurality of applications, and the data fragment comprising a second identifier specific to the application;   at least one processor configured to determine the application on the basis of the first identifier and the second identifier that are received; and   a transmitter configured to transmit the datum to an entity responsible for processing the datum of the application in response to the application being determined.   
     
     
         11 . A device for configuring a packet of a Stream Control Transport Protocol stream transport protocol, the packet comprising a header and a data fragment, the device comprising:
 at least one processor configured to parameterize the packet with a first destination port identifier in the header and with a second identifier specific to an application in the data fragment; and   a transmitter configured to transmit the parameterized packet to a multiplexing device.   
     
     
         12 . (canceled) 
     
     
         13 . At least one non-transitory computer-readable medium comprising instructions stored thereon for implementing a switching method when the program is executed by at least one processor of a multiplexing device, the multiplexing device being able to transfer data relating to a plurality of applications to processing entities, wherein the switching method comprises:
 switching a datum relating to an application transported in a data fragment of a packet of a Stream Control Transport Protocol stream transport protocol, the switching comprising:   receiving, from a terminal device, the packet of the stream transport protocol comprising a header containing a first destination port identifier common to the plurality of applications, and the data fragment comprising a second identifier specific to the application;   determining the application on the basis of the first identifier and the second identifier that are received; and   in response to the application being determined, transmitting the datum to an entity responsible for processing the datum of the application.   
     
     
         14 . At least one non-transitory computer-readable medium comprising instructions stored thereon for implementing a configuration method when the program is executed by at least one processor of a terminal device able to transmit a datum relating to an application to a multiplexing device, wherein the configuration method comprises:
 configuring a packet of a Stream Control Transport Protocol stream transport protocol, the packet comprising a header and a data fragment, the configuring comprising:   parameterizing the packet with a first destination port identifier in the header and with a second identifier specific to the application in the data fragment; and   transmitting the parameterized packet to the multiplexing device.
